1When updating a belongsTo relationship, you may use the associate method. This
2method will set the foreign key on the child model:
3
4 $account = App\Account::find(10);
5 $user->account()->associate($account);
6 $user->save();
7
8When removing a belongsTo relationship, you may use the dissociate method. This
9method will set the relationship foreign key to null:
10
11 $user->account()->dissociate();
12 $user->save();
